Irrigation Methods for Pineapple in Different Regions

arid area

Precipitation is scarce, evaporation is high, and water resources are scarce.

Drip irrigation or sprinkler irrigation should be given priority. Drip irrigation can directly supply water to the roots of pineapple, minimizing water evaporation loss and improving water resource utilization efficiency; Sprinkler irrigation can evenly irrigate pineapple plants by adjusting the spray angle and amount of the nozzle, while also reducing orchard temperature and evaporation to a certain extent. Flood irrigation and spring irrigation are generally less commonly used in arid areas due to significant water loss, unless there is sufficient water supply.

humid areas

Abundant precipitation and high air humidity, but there may be seasonal uneven rainfall.

It is possible to consider using a combination of flood irrigation or spring irrigation with drip irrigation and sprinkler irrigation. During the rainy season, natural precipitation can be utilized to meet the growth needs of pineapples and reduce artificial irrigation; During the dry season or when there is insufficient precipitation, drip or sprinkler irrigation should be selected for supplementary irrigation based on soil moisture conditions to ensure the water required for pineapple growth.

High temperature areas

The temperature is high, evaporation is vigorous, pineapple grows rapidly, and requires a large amount of water.

Sprinkler irrigation and drip irrigation are more suitable. Sprinkler irrigation can lower orchard temperature, increase air humidity, and alleviate the adverse effects of high temperatures on pineapple growth by spraying water; Drip irrigation can provide water to pineapple roots in a timely and quantitative manner, keeping the soil moist and meeting the water needs of pineapples in high temperature environments, while avoiding damage to roots caused by sudden drops in soil temperature due to flooding.

Low temperature areas

The temperature is low, the evaporation is small, and the soil moisture evaporates slowly.

The irrigation frequency should be relatively reduced, and drip irrigation can be used to irrigate the soil in small amounts multiple times according to soil moisture conditions, to avoid excessive irrigation causing low soil temperature and water accumulation, which affects the growth and absorption function of pineapple roots. Flood irrigation and sprinkler irrigation may increase the humidity in orchards at low temperatures, causing pests and diseases. It is generally not recommended to use them unless a small amount of sprinkler irrigation is necessary in clear weather to maintain air humidity and clean plants.
